RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application No.61/928,130, filed Jan. 16, 2014, and U.S. application Ser. No.14/511,964, filed Oct. 10, 2014. The entire contents of theseapplications are incorporated herein by reference in their entirety.

BACKGROUND

Chronic hepatitis B virus (HBV) infection is a significant global healthproblem, affecting over 5% of the world population (over 350 millionpeople worldwide and 1.25 million individuals in the U.S.).

Despite the availability of a prophylactic HBV vaccine, the burden ofchronic HBV infection continues to be a significant unmet worldwidemedical problem, due to suboptimal treatment options and sustained ratesof new infections in most parts of the developing world. Currenttreatments do not provide a cure and are limited to only two classes ofagents (interferon and nucleoside analogues/inhibitors of the viralpolymerase); drug resistance, low efficacy, and tolerability issueslimit their impact. The low cure rates of HBV are attributed at least inpart to the presence and persistence of covalently closed circular DNA(cccDNA) in the nucleus of infected hepatocytes. However, persistentsuppression of HBV DNA slows liver disease progression and helps toprevent hepatocellular carcinoma. Current therapy goals for HBV-infectedpatients are directed to reducing serum HBV DNA to low or undetectablelevels, and to ultimately reducing or preventing the development ofcirrhosis and hepatocellular carcinoma.

There is a need in the art for therapeutic agents that treat, ameliorateor prevent HBV infection. Administration of these therapeutic agents toan HBV infected patient, either as monotherapy or in combination withother HBV treatments or ancillary treatments, will lead to significantlyimproved prognosis, diminished progression of the disease, and enhancedseroconversion rates.

DETAILED DESCRIPTION OF THE INVENTION

Provided herein are compounds that are useful in the treatment andprevention of HBV infection in man. In a non-limiting aspect, thesecompounds may modulate or disrupt HBV assembly and other HBV coreprotein functions necessary for the generation of infectious particlesby interacting with HBV capsid to afford defective viral particles withgreatly reduced virulence. The compounds of the invention have potentantiviral activity, exhibit favorable metabolic, tissue distribution,safety and pharmaceutical profiles, and are suitable for use in man.

The HBV capsid protein plays essential functions during the viral lifecycle. HBV capsid/core proteins form metastable viral particles orprotein shells that protect the viral genome during intercellularpassage, and also play a central role in viral replication processes,including genome encapsidation, genome replication, and virionmorphogenesis and egress. Capsid structures also respond toenvironmental cues to allow un-coating after viral entry. Consistently,proper capsid assembly and function of core protein have been found tobe critical for viral infectivity.

The crucial function of HBV capsid proteins imposes stringentevolutionary constraints on the viral capsid protein sequence, leadingto the observed low sequence variability and high conservation.Consistently, mutations in HBV capsid that disrupt its assembly arelethal, and mutations that perturb capsid stability severely attenuateviral replication. The more conserved a drug target is, the fewerreplication-competent resistance mutations are acquired by patients.Indeed, natural mutations in HBV capsid for chronically infectedpatients accumulate in only four out of 183 residues in the full lengthprotein. Thus, HBV capsid assembly and function inhibitors may elicitlower drug resistance emergence rates relative to existing HBVantivirals. Further, drug therapy that targets HBV capsid could be lessprone to drug-resistant mutations when compared to drugs that targettraditional neuraminidase enzyme active sites. Reports describingcompounds that bind viral capsids and inhibit replication of HIV,rhinovirus and HBV provide strong pharmacological proof of concept forviral capsid proteins as antiviral drug targets.

In one aspect, the compounds of the invention are useful in HBVtreatment by disrupting, accelerating, reducing, delaying and/orinhibiting normal viral capsid assembly and/or disassembly of immatureor mature particles, thereby inducing aberrant capsid morphology andleading to antiviral effects such as disruption of virion assemblyand/or disassembly, virion maturation, and/or virus egress. In oneembodiment, a disruptor of capsid assembly interacts with mature orimmature viral capsid to perturb the stability of the capsid, thusaffecting assembly and/or disassembly. In another embodiment, adisruptor of capsid assembly perturbs protein folding and/or saltbridges required for stability, function and/or normal morphology of theviral capsid, thereby disrupting and/or accelerating capsid assemblyand/or disassembly. In yet another embodiment, the compounds of theinvention bind capsid and alter metabolism of cellular polyproteins andprecursors, leading to abnormal accumulation of protein monomers and/oroligomers and/or abnormal particles, which causes cellular toxicity anddeath of infected cells. In another embodiment, the compounds of theinvention cause failure of the formation of capsid of optimal stability,affecting efficient uncoating and/or disassembly of viruses (e.g.,during infectivity).

In one embodiment, the compounds of the invention disrupt and/oraccelerate capsid assembly and/or disassembly when the capsid protein isimmature. In another embodiment, the compounds of the invention disruptand/or accelerate capsid assembly and/or disassembly when the capsidprotein is mature. In yet another embodiment, the compounds of theinvention disrupt and/or accelerate capsid assembly and/or disassemblyduring vial infectivity. In yet another embodiment, the disruptionand/or acceleration of capsid assembly and/or disassembly attenuates HBVviral infectivity and/or reduces viral load. In yet another embodiment,disruption, acceleration, inhibition, delay and/or reduction of capsidassembly and/or disassembly eradicates the virus from the host organism.In yet another embodiment, eradication of the HBV from a hostadvantageously obviates the need for chronic long-term therapy and/orreduces the duration of long-term therapy.

In one embodiment, the compounds described herein are suitable formonotherapy and are effective against natural or native HBV strains andagainst HBV strains resistant to currently known drugs. In anotherembodiment, the compounds described herein are suitable for use incombination therapy.

In another embodiment, the compounds of the invention can be used inmethods of modulating (e.g., inhibit or disrupt) the activity,stability, function, and viral replication properties of HBV cccDNA. Inyet another embodiment, the compounds of the invention can be used inmethods of diminishing or preventing the formation of HBV cccDNA.

In another embodiment, the compounds of the invention can be used inmethods of modulating (e.g., inhibit or disrupt) the activity of HBVcccDNA. In yet another embodiment, the compounds of the invention can beused in methods of diminishing or preventing the formation of HBVcccDNA.

Compounds of the Invention

The present invention relates to the discovery of compounds that areuseful in the treatment and prevention of HBV infection in man. In oneaspect, the compounds of the invention are useful in HBV treatment bydisrupting, accelerating, reducing delaying or inhibiting normal viralcapsid assembly or disassembly of immature or mature particles, therebyinducing aberrant capsid morphology and leading to antiviral effectssuch as disruption of virion assembly or disassembly or virionmaturation, or virus egress.

In another aspect, compounds of the invention bind to core proteinthereby inducing aberrant virion and leading to antiviral effects suchas disruption of virion assembly, disassembly, maturation, or virusegress.

The capsid assembly disruptors disclosed herein may be used asmonotherapy or in cross-class combination regimens for treating HBVinfection in man. Combination therapy with drugs exhibiting differentmechanism of action (MOA) that act at different steps in the virus lifecycle may deliver greater efficacy due to additive or synergisticantiviral effects. Clinically evaluated HIV treatment regimens haveshown that combination therapy improves the efficacy of viral loadreduction, and dramatically reduces emergence of antiviral resistance.Combination therapy for the treatment of Hepatitis C (HCV) virusinfection has also resulted in significant improvement in sustainedantiviral response and eradication rates. Thus, use of the HBV capsidassembly inhibitors of the present invention in combination with, forexample, neuraminidase drugs, is likely to deliver a more profoundantiviral effect and greater disease eradication rates than currentstandards of care.

Capsid assembly plays a central role in HBV genome replication. HBVpolymerase binds pre-genomic HBV RNA (pgRNA), and pgRNA encapsidationmust occur prior to HBV DNA synthesis. Moreover, it is well establishedthat nuclear accumulation of the cccDNA replication intermediate, whichis responsible for maintenance of chronic HBV replication in thepresence of nucleoside suppressive therapy, requires the capsid forshuttling HBV DNA to the nuclei. Therefore, the HBV capsid assemblydisruptors of the invention have the potential to increase HBVeradication rates through synergistic or additive suppression of viralgenome replication and to further reduce accumulation of cccDNA whenused alone or in combination with existing nucleoside drugs. The capsidassembly disruptors of the present invention may also alter normal coreprotein function or degradation, potentially leading to altered MHC-1antigen presentation, which may in turn increaseseroconversion/eradication rates through immuno-stimulatory activity,more effectively clearing infected cells.

In one aspect, drug resistance poses a major threat to current therapiesfor chronic HBV infection, and cross-class combination therapy is aproven strategy for delaying emergence of drug resistance strains. Thecapsid assembly disruptors of the present invention can, whenadministered alone or in combination with other HBV therapy, offerenhanced drug resistant profiles and improved management of chronic HBV.

The compounds useful within the invention can be synthesized usingtechniques well-known in the art of organic synthesis. The startingmaterials and intermediates required for the synthesis may be obtainedfrom commercial sources or synthesized according to methods known tothose skilled in the art.

In one aspect, the compound of the invention is a compound of Formula I:

or a pharmaceutically acceptable salt thereof;

Example HBV Assembly Assay

The fluorescence quenching in vitro assembly HBV assay was developedaccording to a method described by Zlotnick and coworkers (NatureBiotechnology 2006, 24:358). The assay is based on the observation thatthe C-termini of the HBV core protein cluster together during capsidformation. This assay utilizes a mutant C150 HBV capsid protein whereall wild-type cysteines are mutated to alanines, but a C-terminalcysteine residue is preserved and is labeled with fluorescent BoDIPY-FLdye. HBV C150Bo protein is highly fluorescent, however the fluorescenceis drastically reduced during the capsid assembly process. Thus, theassay measures the ability and potency of test compounds to modulatecapsid assembly by monitoring the fluorescence of the labeled capsidC150Bo protein.

In a typical assay, the mutant HBV C150 protein (amino acids 1-150,C49A, C61A, C107A, 150C) is cloned into a T7 RNA-polymerase basedexpression vector, expressed in E. coli and purified to homogeneity as adimer. The purified HBV core protein is desalted and labeled withBODIPY-FL Dye.

In a non-limiting embodiment, the assembly assay is conducted in 96-wellplate format. The assembly reactions are carried out in 50 mM Hepesbuffer, pH 7.5 and 150 mM NaCl. The compounds are pre-incubated with theHBV CA protein for 15 min, and the assembly reactions are initiated byaddition of NaCl. The reaction is allowed to continue for 1 hour at roomtemperature.

To determine the effect on capsid assembly, each test compound isinitially screened at least 4 different concentrations in duplicates.Primary hits are compounds that show activity in the assembly assay at10 uM. Identified primary hits are confirmed in follow-up studies asdescribed elsewhere herein. Known modulators of HBV CA assembly, such asHAP-1 and BAY 41-4109, are used as control compounds in theseexperiments and exhibited EC₅₀ values consistent with the literature.EC₅₀ values for test compounds are determined via analysis of thedose-response curve.

Selected compounds of the invention were assayed in the HBV assemblyassay, as described above. The assembly assay was conducted in 96-wellplate format. The assembly reactions were carried out in 50 mM Hepesbuffer, pH 7.5 and 150 mM NaCl. The compounds were pre-incubated withthe HBV CA protein for 15 min, and the assembly reactions were initiatedby addition of NaCl. The reaction was allowed to continue for 1 hour atroom temperature. The 96-well plate assembly assay consistently had Z′factors greater than 0.7 and were robust and reproducible both fromplate-to-plate and day-to-day.

To determine the effect on capsid assembly, each test compound wasinitially screened at 5 different concentrations: about 30 μM, 10 μM, 3μM, 1 μM, and 0.3 μM in duplicates. Primary hits were compounds thatshow >50% activity in the assembly assay at about 10 μM and arepresentative group of these active compounds is shown in Table 4.

Example Inhibition of HBV Replication Dot-blot Assay

Compounds active in the HBV assembly assay are tested for their activityand toxicity in cellular assay. In the first anti-viral assay, theability of compounds to inhibit HBV replication in an HBV-producinghepatoma cell line using the dot-blot method is evaluated.

Briefly, confluent monolayers of HepG2-2.2.15 cells are incubated withcomplete medium containing various concentrations of a test compound.Three days later, the culture medium is replaced with fresh mediumcontaining the appropriately diluted test compound. Six days followingthe initial administration of the test compound, the cell culturesupernatant is collected, and cell lysis is performed. The samples areapplied onto Nylos membranes and DNA is immobilized to the membrane byUV cross-linking. After pre-hybridization, the HBV probe is added andthe hybridization is performed overnight. The membranes are exposed tothe Kodak films; antiviral activity is calculated from the reduction inHBV DNA levels (EC₅₀). The EC₅₀ for antiviral activity is calculatedfrom the dose response curves of active compounds. Assay performanceover time is monitored by the use of the standard positive controlcompounds ETV, BAY 41-4109, and HAP-1.

Compound cytotoxity (TC₅₀) is measured in this same HepG2-2.2.15 cellline using a CellTiter Blue-based cytotoxicity assay employed asrecommended by manufacturer (Promega). To confirm and expand theseresults, a second antiviral assay is carried out on active compoundsusing the stable HBV cell line HepG2.2.15 and measuring anti-HBV potencyby real-time PCR and cytotoxicity by CellTiter Blue. In this assay, 24hours after cell seeding, HepG2-2.2.15 cells are incubated with completemedium containing various concentrations of a test compound with BAY41-4109 and HAP-1 used as positive controls. After three days, theculture medium is replaced with fresh medium containing theappropriately diluted test compound. The cell culture is collected sixdays following the initial administration of the test compound, followedby HBV DNA extraction using QIAamp 96 DNA Blood Kit (Qiagen). Theextracted HBV DNA is diluted and analyzed by Real-Time PCR. A standardcurve is generated by plotting Ct value vs the amount of HBV plasmidstandard. Cytotoxicity is determined similarly to the above describedmethod by applying a dye uptake method (CellTiter Blue kit, Promega).
